简要总结
The aim of this 2-stage, 3-site study is to investigate the effectiveness and safety of a combination of extended-release depot naltrexone plus extended-release bupropion as a potential pharmacotherapy for methamphetamine (MA) use disorder.
详细描述
Stage 1 will include 20 individuals with severe stimulant use disorder (methamphetamine type) enrolled across three study sites. Following a maximum 30-day screening period to establish eligibility, participants will receive a monthly injection of extended-release depot naltrexone (XR-NTX; as Vivitrol®) plus once-daily bupropion extended-release tablets (BRP; as Wellbutrin XL®) for 8 weeks. Take-home oral study medication (BRP) will be dispensed weekly for dosing on non-clinic days. Participants will be asked to attend clinic twice weekly for observed BRP dosing, collection of urine samples, assessments, and medical management. Following the 8-week active medication phase, participants will complete a follow-up phase, including a medication taper and post-medication phase follow-up visit during Week 9. If Stage 1 data document success (see criteria below) in at least 3 "responder" study participants, Stage 2 will follow utilizing the same protocol as in Stage 1, to enroll an additional group of 29 participants. Using the same criteria of "responder" success, if the combined stages document success in at least 9 of 49 study participants, the combination medication will be considered to have shown sufficient potential to advance to a large-scale placebo-controlled trial.
